Is the use of binoculars to maintain visual line of sight with an sUAS operation compliant with 14 CFR Part 107?

The operation of a small unmanned aircraft system (sUAS) must comply with the regulations outlined in 14 CFR Part 107, which includes maintaining a visual line of sight (VLOS) with the aircraft during operation. VLOS means that the remote pilot or the visual observer must be able to see the aircraft with their own eyes, without the aid of any devices that enhance vision, such as binoculars or telescopes.

Using binoculars to maintain visual contact would not satisfy the VLOS requirement, as it is explicitly stated that the pilot must be able to view the aircraft directly. The regulation is designed to ensure that the operator can see the aircraft's position, direction, and condition to ensure safety and situational awareness. Therefore, the operation would not be compliant with Part 107 if binoculars are used for this purpose.

The other choices imply conditions or exceptions that are not supported by the regulation. For example, merely being able to see the aircraft or having a distance consideration does not change the essential need for direct visual contact without enhancements. Additionally, the time of day—whether during daylight—does not impact the requirement regarding the use of visual aids.
